SIGNAL.

Specification of Letters Patent. P t t 1922 Application filed January15, 1819. Serial No. 271,283.

To all who mitt may concern:

Be it known that I, ALBERT LEE ELIEL, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Signals, ofwhich the following is a specification.

This invention relates to signals, generally, and more particularly tovehicle signals, whereby the drivers of automobiles and other vehiclesmay indicate the direction in which a turning movement of the vehicle isto be executed. Many devices of this character have been previouslyexperimented with, and the invention has for its object to provide asimple, inexpensive, attractive, reliable, conveniently operated,positive and practical device of this character, which may be used inlong continued service without failure and which in the respectsmentioned will be superior toprevious devices attempted to be operated.With the above and other objects in view, the invention consists in thenovel and useful formation, provision, combination, association andrelative arrangement of parts, members and features, all as hereinafterdescribed, shown in; the drawings, and finally pointed out in claims.

In the drawings:

Figure 1 is a fragmentary rear elevation of a portion of the dashboardand of the windshield of a motor vehicle, showing the signal device ofthe invention installed, in two units, in connection with suchdashboard;

Figure'2 is an enlarged rear side elevation of one of the signal devicesshown in Figure 1, in detached position;

Figure 3 is a diagrammatic view illustrating the source of electricalenergy and the electrical path for such energy, all employed in theoperation of an audible signal member and a visible signal member usedin connection with the signal device of the other features;

view taken upon the line 0010-44010, Figure 2, and looking in thedirection of the appended arrows;

Figure 11 is a detail sectional view of features of the constructionshown particularly in Figure 6, the same being fragmentary, and takenupon the line cull-a 11, Figure 6, and looking in the direction of theappended arrows;

Figure 12 is an end view of the construction shown in Figures 2 and 4,looking in the direction of the large arrow at the right hand end ofFigure 4; and, 1

Figure 13 is an isometric view of an elemerit of the signal device shownin Figures i, 2 and 4, the same being in detached posi- Correspondingparts in all the figures are designated by the same referencecharacters.

Referring with particularity to-the drawings, theimproved signal thereindisclosed comprises a casing or housing A, a signal member B; normallyhoused or chambered therein and adapted to be projected therefrom intosignalling position, means of illumination C carried by said signalmember, and an audible signal means D within said housing or casing. Twoof such signals are shown as mounted upon the dash E of a motor vehicle,in Figure 1, one at each side of the dash, so that the signal members Bof the same may be respectively projected to left and to right intosignalling positions. The casings or housings A are provided with ears14 for attaching the same to such dash. F designates switch meansmounted upon the dash and whereby the signal means C' and the signalmeans I), or the signal means D alone, may be operated, by electricalenergy from. a source G, such as a battery, or

from the electrical circuit used in operating the motor vehicle. Theaudible signal l) ma comprise the usual electro-magnetically operatedbell 15, of any standard or preferred form, the same being mountedwithin the casing hat the end thereof opposite to that from which thesignal member B is projected. 1

The signal member B is preferably composed of a pair of metallic plates16, which are stamped out of sheet metal plates, and are oppositelybowed in their median portions, as at 16*, to producea central chamber16? within which may be accommodated the various features of circuitwiring,- and the like, hereinafter outlined in detail, At the outer endof this signal member B is provided the lighting signal means C, thesame preferably consisting of an ordinary meandescent bulb l? which .lSaccommodated in an opening 17 produced through the outer end portionsOIlE lJllG plates 16, such incandescent bulb being fitted into the usualsocket, accommodated within an enlargement 16 of the chamber 16 producedby increasing the lateral bulge'of each plate 16. These plates 16 aresuitably secured togethenas by rivets 18 and the top and bottom edgeportions of the" joined plates 16 are provided with opposed ears 16which ointly prov de i projections received within ways 1.9 formed inthe top and bottom of thecasing or'hous ing A, such waysbeing'preiferably 'merely channels in the metallic formation of suchcasing. The bulb 17 is held detachablyin place by a pair of curvedspring lingers 21, each of which is secured to one of theplates 16, at20, and embraces the neck of the bulbat one side, acting as a guard andsafety means forfholding thebulb firmly in position. H designates anoperating member for the signal member B, the consisting of a rodiorarm'22 which is secured at one end, as at 23, to the-signal niemberB,

-the same being curved outwardly and entended parallel with the casing Aand terminated at the other end in a finger piece or hand-hold '22, andbeing confined by a keeper 24: which is at the end of an elongated slotor opening 25 produced in the outer side wall of the casing'A, and whichpermits the rod 22 to travel jointly with the projection and retractionof the member B, The rod is secured to the sliding member B as shown inFigures 6 and 11 ineetail, being provided with a reduced end portion222" which passes through the plates 16 of? the member B at thebulgingportions 16 there of, there being a washer 22 passed upon suchreduced'end portion and accommodated within the chamber 16. Betweenwashers 28 at the extreme end portion. of such refrom the top thereof.

duced end portion 22 is secured one end of a contact linger 27, w richhas a brushing contact with an elongated circuit member 28 held withinthe casing A and depending An end nut 29 is ap plied to a still furtherreduced and threaded portion. 30 at the end of the rod 22, thus holdingthe contact member 27, the nuts 26,

We washer 22 and the rod 22, all in assemblage in connection with themember B and its plates 16. K'designates a door or closme for the outerend of the casing A, the same being a drop door connected with thetopwall of the casing by a spring hinge 31 so that it will automaticallyremain closed when the member Bis housed.

in order to energize the lamp 1'! and the bell 15, so that the means Cand D may be operated in signalling, suitable electrical circuitymembersare provided. These are part of an electrical. path k, which extendsfrom the switch F to and through the battery or other electrical energysource G, to and through the electromagnetic element or the bellsignalD, and to and through the incandescent lamp bulb element of thesignal means C. This electrical path includes and comprises anypreferred and suitable con.- ducting members, including insulated wires,and those which supply the lamp 17 extend within the chamber 16 in themember B. ilS'ShOWll the diagrammatic representat-ion in Figure 3, theelectrical path extends the electrical Jath and ener ize the bell 15while de-energizing the light 1 7 or to close circuit throughtheelectrical path and energize both the bell l5 and the'lamp 17.

In the operation of the device, the switch is operated to cause theoperation 01" either the bell alone or the lamp and bell together, inaccordance with Whether the pe- 'riod of use he one of darkness orlight.

Then, when it is desired to set the signal, the switch having so beenoperated, the operating member H is rasped at the hand-hold and themember B is projected into visible position, at one side or the other ofthe vehicle, the operation of both of the signals being the samebut/only one being used, and at the proper side, at any one time. Whenthe bell-l and lamp are jointly operated, the interruptions in theelectrical path caused by the intermittent action in the-electromagneticmeans operating the bell, will cause pulsations in the light emitted bythe lamp 1? and this will produce a lighting effect in the same from anyother lamp or light upon the roadway. This pulsating light effect will,in extended use of the invention, be associated by drivers andpedestrians with the use of a signal of this type, and thus the signalwill be far more effective than it would be were the light of the usualnonpulsating or steadily-burning type.

It is manifest that many variations may be made in practicing theinvention, in departure from the exact construction shown in thedrawings and described in the preceding description. All this variationmay take place without departing from the real spirit of the invention.

Having thus disclosed my invention, I claim and desire to secure byLetters Patent:
